When compiling with cuda and tbb enabled in a single translation unit you
need to make sure all try/catch blocks are marked as host only otherwise
the cuda compiler will error out.
Previously it was really hard to verify if a device adapter was valid. Since
you would have to check for the existence of the tag. Now the tag always
exists, but instead you query the traits of the DeviceAdapter to see if
it is a valid adapter.
This makes compiling with multiple backends alot easier.
Add ArrayHandleIndex
Add an ```ArrayHandleIndex``` class that echoes the index. This is really a special version of ```ArrayHandleCounting``` that is of type ```vtkm::Id``` and starts at 0, but it is the most common case and does not need the extra addition.
Also modified ```ArrayHandleCounting``` to support a step, which makes the use a bit more powerful.
See merge request !192
Modify ArrayHandleCounting so that it supports both a starting value and
a step (increment). This adds a multiplication, but the common case that
does not use it is already in a separate class (ArrayHandleIndex).
Template the splatter algorithm over Kernel type and use abstract kernel
interface to fetch the kernel value.
Add Gaussian, Spline3rdOrder kernel classes templated over dimension.
Other kernels can/will be added in future.
Kernel classes are defined such that the integral of the volume is unity
as is the convention in (for example) SPH simulations.
Clean up the implementation to take a uniform grid dataset as input
and splat using the correct world coordinates of the points into
the volume. Kernels are centred around the splat points in world coordinates
(floating point) and not quantized to the nearest voxel.
Skip the generation of all volume points which is unnecessary (memory usage).
Add ability to specify a radius array with one entry per splat point so
that the size of each splat may be controlled arbitrarily.
Change ExecutionWholeArray interface to match expected for ArrayPortal
When ExecutionWholeArray is passed to a worklet, it is expected to
behave like an array portal. However, it was missing the
GetNumberOfValues method and the ValueType typedef. These are now added.

c75facf9 Add a HelloWorld example that uses opengl interop.

Update VTK-m to export to Configure.h if we have opengl interop enabled.
At the same time I rearranged the CMakeLists.txt so that the configuration
for Configure.h is later so that it catches all CMake Variables.
